What are the Different Sizes and Types of Speculum?

By admin  | In Cyalume Blog,Frequently Asked Questions

Understanding Features and Benefits of Each Speculum Type

Typically made of plastic or medical, the cervical speculum is a tool developed in the 1800s and used still today by OB/GYNs. There are other types of speculum, such as the nasal variety, used to remove foreign bodies from body cavities, but those will not be our topic of focus. There are three main types of cervical speculum: pediatric, Pederson and Graves.

The Pediatric Speculum

Shorter in length, the pediatric speculum is intended for use in patients who have never had sexual intercourse and therefore have narrower vaginal canals. A common misconception is that the pediatric speculum is used to conduct pediatric vaginal examinations; this isn’t true. Use of a speculum in a pediatric exam could be traumatic for both the child and the parent and therefore the practice is avoided.

The Pederson Speculum

Flat and narrow, the Pederson speculum is a vaginal speculum used during OB/GYN examinations when women have narrow vaginal canals. This condition can be caused by traumatic injuries and the resulting scar tissue, but is also found in elderly women and women who have never had sexual intercourse. Using this narrow speculum type can eliminate some of the discomfort of a pelvic exam.

The Graves Speculum

The Graves speculum is the most common variety used by OB/GYNs. This vaginal speculum is commonly available in multiple sizes: small, medium and large. The bills of the Graves speculum, which resemble a duck’s mouth, are wider than the bills of the Pederson speculum, and the sides are also curved. According to the University of Washington, this type of speculum is best used in women who have had sexual intercourse. This is because the vaginal canal may be wider in sexually active women, making the wider bills of the Graves speculum necessary to visualize the cervix and other internal structures of the pelvis.

What Type of Speculum is the SpecuLume?

The SpecuLume is a Graves-style speculum available in small, medium and large sizes. Unlike traditional plastic and metal specula, the SpecuLume integrates a chemiluminescent light source which allows OB/GYNs to safely deliver bright light directly to the examination area without the encumbrance of typical light sources.

Or, What is a vaginal speculum and how does chemiluminescence increase its effectiveness?

A traditional vaginal speculum, made of metal or sometimes plastic, consists of a hollow cylinder with a rounded end that is divided into two hinged parts. Somewhat resembling the beak of a duck, the vaginal speculum was created by J. Marion Sims for use during examination of the vagina and cervix. 

This device, pioneered in the 1840’s, has largely gone unchanged since its inception, though adoption of plastic specula, instead of sterilized metal versions, has increased outside of surgical suites. Traditionally, the speculum is paired with an external light source. External light sources include floor lamps, pen lights, head lamps and lights integrated into glasses. 

The Cyalume SpecuLume adds an unrealized convenience to OB/GYN procedures as it combines the proven speculum design with an integrated, non-heat-generating light to deliver illumination directly to the examination area. Made of plastic, this SpecuLume is single-use, virtually eliminating the risk of cross-contamination. 

The most novel development is the light source. Illumination is provided by the process of chemilumination – the same process that powers glow sticks. Cyalume knows a thing or two about chemical light; after all, we invented the technology. 

Since then, our research and development team has spent decades making chemical light as safe and reliable as possible. Today, clinicians can perform examinations more efficiently and effectively with the help of a 100% non-toxic, no-heat-generating source of light exactly where they need it without having to position and re-position an external light source. 

The light is emitted from a small chemiluminator located at the tip of the “bill.” Clinicians simply bend, shake and insert the chemiluminator to activate the process, which will provide light for approximately 20 minutes. 

For OB/GYN practitioners interested in using metal specula, we also offer the chemiluminator with an adhesive backing – the OnLite. Whether SpecuLume is an all-in-one solution for you, or you’d like to integrate OnLite into your existing specula rotation, we encourage you to learn more about our products.

Cyalume SpecuLume: How Does it Work?

By admin  | In Cyalume Blog,Frequently Asked Questions,SpecuLume

How To Use a Speculum with Integrated Chemiluminescent Light Source

When performing vaginal examinations, clinicians currently have two options. The first option combines a traditional speculum, in either plastic or metal, with an external light source like a floor lamp, pen light or head lamp. This approach provides a cumbersome experience, to say the least.

The second option for speculum exam is a disposable lighted version utilizing LED technology. This also means batteries or electricity are needed. Furthermore, the light from LEDs is often harsh, washing out the exam area.
The SpecuLume is a clear, plastic, single-use speculum that combines the best of each approach to provide ideal illumination with chemiluminescence technology. The clear nature of the device allows vivid light to reach the entire examination area instead of a focused beam.

How Our SpecuLume Works

To activate a SpecuLume, a clinician simply bends the luminescent cartridge to ignite it and inserts it into the speculum for instant illumination that lasts up to 20 minutes without the need for batteries or electricity. Post-examination, the clinician can simply discard the entire unit as clinical waste, virtually eliminating the risk of cross contamination.

how to use speculume

Within the luminescent cartridge, two key solutions are kept separate by a thin glass ampule that breaks during the bend and shake phase of activation. At that point, Oxalate Ester and Hydrogen Peroxide combine to produce chemical energy, and the rate of the reaction is controlled by a Catalyst. The last piece of the solution, a Fluorescer, absorbs the chemical energy and converts it to light, the color of which is determined by the Fluorescer employed.

Cyalume SpecuLume vs Meta Speculum



What Makes the SpecuLume Better Than Other Types of Speculum?

By admin  | In Cyalume Blog,Frequently Asked Questions,SpecuLume

How to Use a Speculum with Integrated Chemiluminescent Light Source

Generally speaking, the speculum has been around since the 1800’s. While there hasn’t been much advancement in terms of design, the use of disposable speculum has become more widespread in recent decades. Still, the design, having been proven over the course of more than 150 years, hasn’t changed. So how could such an established tool be improved upon?

LED lights have become increasingly popular as a means to illuminate the examination area during OB/GYN procedures where specula are employed. Surely, this is an improvement over an external floor lamp or pen light. The trouble is, LED lights require batteries or electricity, and, even worse, their harsh light often proves to be too much – washing out the area surrounding their direct beam.

Having invented chemical light, the science behind glow sticks, in the 1960’s, Cyalume Technologies sought to leverage their research and development team to come up with a better solution for OB/GYN clinicians to compete with other types of speculum.

What Makes SpecuLume the Best Disposable Speculum?

There are five reasons clinicians should choose SpecuLume over traditional and disposable options available today.
Latest Technology – newly developed chemiluminescent technology allows optimal light to be discreetly delivered directly to the examination area without batteries or electricity

  1. High Efficiency – SpecuLume, not reliant on outside power sources, will provide consistent results regardless of setting or the availability of power
  2. Easy to Use – Precise and simple design allows clinicians comfort and confidence from the first use. Activation is as easy as bend and shake
  3. Proven Track Record – Cyalume Technologies invented chemical light and has introduced many medical innovations to the marketplace. SpecuLume is a marriage of these two aptitudes
  4. Affordable – Achieve lower operational costs thank to no cleaning, disinfecting or sterilizing necessary. Stop wasting time on non-patient-centric tasks

How to Dispose of a Cyalume SpecuLUme



How to Process a Disposable Speculum Like the Single-Use SpecuLume

By admin  | In Cyalume Blog,Frequently Asked Questions,SpecuLume

Many times, we’re asked one of two questions, usually both:

Does this product require special discarding after use?
Can it be reused?

In terms of special disposal, the answer is no. Our disposable speculum requires no disassembly or deactivation. Simply toss the entire device into the clinical waste container. There are no chemicals, batteries or hazardous waste management requirements that require special care.

In terms of reuse, the answer is also no. The light cartridge is designed for a single activation. To minimize the risk of cross-contamination, all our products are single-use. Furthermore, cleaning a single-use product for reuse will negate the time and expense savings gained by choosing single-use in the first place.

Learn More About the SpecuLume

The SpecuLume uses proprietary chemiluminesence technology to deliver brilliant lighting where it is needed most, at the tip of the speculum, filling the examination area with functional light. The clinician simply “snaps” the luminescent cartridge to activate the illumination and inserts it into the speculum for instant bright light lasting up to 15 minutes.

The SpecuLume is a vast improvement on available technology. Today, when performing vaginal examinations clinicians use either speculums along with an external light source (floor lamp, head lamp, pen light), or a disposable lighted speculum using LED illumination that requires electricity or batteries.

These light sources can either be harsh, not sufficient, or difficult to orient in order to be able to see the examination area. With its 360-degree diffused illumination, light emitted from the SpecuLume’s illuminator is ideal for clinical examinations.

When the examination is complete, the clinician simply discards the product as clinical waste without worry or special attention. The SpecuLume is sold non-sterile but comes in packaging that allows for ethylene oxide sterilization. Additionally, the SpecuLume is available in small, medium and large sizes.
